Hello Virtuali,
With version V3.6.8 and having fully understood this change:
Page 49 : "
In version 3.6.8, the behavior of the Shift key has been changed, to act as a “Toggle”, switching between a Fast (default) or a Slow move/rotate/raise speed, this to prevent MSFS from sending both a Shifted and Unshifted commmand, causing errors. Also, the keys to Raise/Lower objects has been changed to PgUp/PgDn."
When I want to move a Marshaller or other vehicles, whether I'm in SLOW or FAST (displayed on the screen), the object's movement speed doesn't change (marshaller very slow, vehicle too far apart).When I want to move a Marshaller or other vehicles, whether I'm in SLOW or FAST (displayed on the screen), the object's movement speed doesn't change (marshaller very slow, vehicle too far apart).
Page 50 : "
PgUp/PgDN Increase/Decrease the object height from ground. This will be used to adjust the height from ground for several types of Visual Docking System types, which are wall-mounted."
Furthermore, to place a Visual Docking System types, the [Page Down] and [Page Up] keys have no effect on the object. [Edit : after checking, it works for objects in the air]

Could you please provide an explanation or help? Thank you in advance.
